WIRE-WORKING mPIEMENT.

I Specification of Letters Patent.

Patented July 18, 1909.

To all whom it may concern:

Be it known that I, CLARK J. SMITH, residin at Ottumwa, in the county ofWapello and tate of Iowa, have invented certain new and useful Imrovements in Wire-Working Implements, 0 which the following is aspecification.

My invention relates to certain new and useful improvements inimplements for cutting, forming and applying wire fastenings to ose pipecouplings and my invention has for its 0 ject to provided a simple andeffectively constructed implement whereby a fastener wire may be bentinto sha e while a second wire is applied to the coup ing and a thirdwire is being out.

The invention also has for its object to provide an implementwherein thefastener wire may be cut, bent and applied by one and the sanlieimplement without the use of auxiliary too s.

More speeificallltv the invention embodies those novel deta' s ofconstruction, combination and arrangement of parts all of which will befirst described in detail and then he s ecifically pointed out in theappended c ims, reference being had to the accompanying drawings, inwhich Figure 1 is a perspective view showing how my invention may beused to simultaneously apply a wire to the coupling, form another wireand cut a third wire. Fig. 2 is a central, vertical, longitudinalsection of the coupling, the parts being shown in one posi tion. Fig. 3is a similar view, the parts being in another position. Fig. 4 is a topplan Fig. 5 is a vertical longitudinal section on the line 55 of Fig. 4.Figs. 6 and 7 are cross sections on the line 66 of Fig. 4, looking inthe direction of the arrows :4: and y res ectively. Fig. 8 is a rearelevation of my implement. Fig. 9 is a detail perspective view of themain frame. Fig. 10 is a similar view of the sliding carriage. Fig. 1 1is a detail erspective view of the wire clamping end of t e carriage.

Referring now to the accompanying drawings in which likeletters andnumerals of reference indicate like parts in all of the figures, 1designates the main frame which is provided with aT-shaped channelformed by the bottom 1*, sides 1 a and the bent over top edges 1 At thefront of the frame 1 the sides Pare provided with alining depressions 1that are curved as at 1 to form cam surfaces and the depressions 1 mergewith depressions 1' 1n the opposmg faces of the bent over ends 1, asclearly shown in Fig. 9 of the drawings.

The bottom 1 near the front end is provided with perforations 1 whichregister with perforations 2 in the sliding carriage 2 to form a cuttingmechanism. At the rear the main frame 1 is provided with a back plate 1which carries an anvil 1 that has a groove 1 fora purpose hereinaftermore clearly understood and the back plate 1 is provided withlongitudinal alining apertures 1 through which the ends of the wire 'wmay be passe The carriage 2 is provided on its upper face with rackteeth 2", the front ones of which are cut away, as at 2, to leave aspace between the rack teeth 2 and the adjacent edges of the bent overends 1 of the main frame 1, the space being slightly more thanthe-thickness of the wirew. The front rack member 2 is provided withslightly beveled ortions 2 to receive the wire w when it is ent intoform to revent it slipping off the member 2". At tiie rear the carriage2 has grooves 2 and a bearing lug 2 to which a cam grip lever 3 ispivoted at 3, the lever 3 having serrated cam surfaces 3 to enter thegrooves 2. The grooves 2, it should be understood, aline with theapertures 1 in the back plate 1 of the frame 1 so that when the wiresare projected through the apertures 1 they will project into the grooves2 and may be grip ed by the cam lever as shown in Fig. 2 of tiledrawings.

The main frame 1 has ears 1 through which the pivoted ends 4 of thelever 4 pass, the lever 4 being provided with a segment 4* to mesh withthe rack teeth 2 so that as the lever 4 is manipulated to turn thesegment 4 .on its axis the carriage 2 will be reciprocated in the frame1.

In the practical application of my invention the wire is cut into aproximately the desired lengths, and it is tiien placed in thedepressions 1 of the main frame 1, it being understood that the carriage2 is drawn to its, backmost position. The lever 4 is then moved in thedirection of the arrow in Fig. 2, causing the carriage to be forwardlydirected, thus bringing the front rack tooth 2 into engagement with thewire and thereby carrying it along and causing it to be' bent into aU-shape. The wire rests in the depressions 1, as it is formed, while thecam surfaces 1 serve to raise the ends of the wire clear of the frame 1,as it is, being bent into the U-shape, so that the wire will lieadjacent to the teeth 2 in the cut-away portions 2 thereof. Upon movingthe lever 4 in an opposite direction to turn the carriage 2 to itsbackward position, the formed wire willbe released. In forming the Wirethe two legs of the U are not always of the same length so it becomesnecessary to trim them off or they may be longer than is desired, andmay need trimming off for that reason. In order to trim the wire to theroper length after it is formed into the U-diape, the ends are passedthrough the apertures 1 in the bottom 1 of the main frame 1 and throughthe apertures 2 of the carriage 2, it being understood that the aertures 2 and 1 are first brought into ainement. As soon as the Wire hasbeen projected through such a ertures 1 and 2 the desired distance, t elever 4 is brought down to project the carriage forwardly, causing thewire ends to be cut or broken. After the wire has been formed intoU-shape, it is bent around the hose coupling in the usual manner withthe ends projected through the loops and the ends of the wire are thenassed through the a ertures 1 and clamped by the clamp 3, after whichthe lever 4 is brought down to move the carriage forward. This bringsthe portion w of the wire into the saddle 1 and as the carriage movesforwardly the wire will be tightly drawn around the coupling.

As soon as the wire has been drawn taut the coupling is rolled aroundthe anvil 1 until the wire is bent to hold it from slipping.

After which, the wire is released from the clamp 3, withdrawn and bentdown by using the implement as a hammer in any desired manner. A Wiremay be bent into a U shape while a second Wire is being cut and a thirdwire isbeing applied to the hose cougling, by one and the same movementof t e lever 4, as indicated in Figs. 1, 2 and 3 of the drawings.

From the foregoing description, taken in connection with theaccompanying drawings, it is thought the complete construction,operation and advantages of my invention will be readily understood bythose skilled in the art to which the invention appertains.
